Density

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find mass using density and volume?

Back

Mass = Density × Volume.

Front

What is the formula to find volume using density and mass?

Back

Volume = Mass / Density.

Front

If a substance has a density of 10 g/cm³ and a volume of 5 cm³, what is its mass?

Back

Mass = 10 g/cm³ × 5 cm³ = 50 g.

Front

What is the density of an object with a mass of 20 g and a volume of 4 cm³?

Back

Density = 20 g / 4 cm³ = 5 g/cm³.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

What tool is commonly used to measure the volume of liquids?

Back

Graduated cylinder.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.

Front

If an object has a density greater than 1 g/cm³, will it sink or float in water?

Back

It will sink.
